LC79431KNE

Ordering number : ENA2124 LC79431KNE CMOS LSI Dot-Matrix LCD Drivers http://onsemi.com Overview The LC79431KNE is a large-scale dot matrix LCD common driver LSI. The LC79431KNE contains an 80-bit bidirectional shift register and is equipped with a 4-level LCD driver. The input/output pins for cascade connection can be used to further increase the IC’s number of bits. The LC79431KNE can be used in conjunction with segment driver LC79401KNE (QIP100E) to drive a wide-screen LCD panel. Features On-chip LCD drive circuit (80 bits) Display duty selection ranging from 1/64 to 1/256 On-chip input/output pins support a further increases in bit number Supports externally supplied bias voltage Operating power supply voltage/operating temperature include VDD (Logic section) : 2.7 to 5.5V/-20 to +85°C VDD-VEE (LCD section) : 12 to 32V/-20 to +85°C CMOS process 100-pin flat plastic package (QIP100E) Semiconductor Components Industries, LLC, 2013 July, 2013 91912HKPC 20080310-S00005 No. A2124-1/7 LC79431KNE Specifications Absolute Maximum Ratings at Ta = 25±2°C, VSS = 0V Parameter Symbol Conditions Ratings unit Maximum supply voltage (Logic) VDD max -0.3 to +7.0 V Maximum supply voltage (LCD) VDD-VEE max *1 0 to 35 V Maximum input voltage VI max -0.3 to VDD+0.3 V Storage temperature Tstg -40 to +125 °C Note *1 The following relations between elements should be maintained: VDD≥V1>V2>V5>VEE, VDD-V2≤7V, V5-VEE≤7V Stresses exceeding Maximum Ratings m...
